Date Jan. 3, 1997The present invention provides novel hydroxylamine derivatives represented by the general formula: wherein: X is O, -NH, or a group of formula NR', wherein R and R' are independently selected from alkyl, cycloalkyl, phenylalkyl, phenyl optionally substituted with halo, haloalkyl, alkyl, alkoxy or nitro; and a N-containing heterocyclic ring; R1 is H or alkanoyl, R2 is H or hydroxy optionally acylated with alkanoyl, and R3 is a group of the formula -NR4R5 wherein R4 and R5 are independently selected from H, alkyl, and a group of the formula -CO-NH-R wherein R is as defined above, or wherein R4 and R5 when taken together form a 5- to 7-membered heterocyclic ring which may optionally contain one additional hetero atom selected from nitrogen, oxygen and sulfur and which is optionally substituted with alkyl or phenylalkyl. Also provided are pharmaceutically acceptable acid addition salts of the compounds defined above, as well as pharmaceutical compositions containing the compounds or their acid addition salts as active ingredients. The compounds of the invention have been shown to have anti-ischemic effects.
